I was just chatting with someone who has one of these, as I want one. They are affordable. What was recommended to me was as little as 2 mins at a time when starting out. They have a lot of drag and are uphill. Going slow is key.

I had this site saved but then my comp decided to blow up! Thanks so much!!

Ohhh yes I know, Slow is the way to go, I dont want to hurt my babies, I just want to let them get some exercise since its WAY to hot to exercise here except late at night, and well I dont feel like running in to the wrong person.....Thanks so much, These prices are SO awesome!
